Department of Microbiology, Kurume University School of Medicine Kurume, Japan The effects of heating, ultraviolet irradiation, and agitation on the infectious activity of Myc. lepraemurium were investigated. The results obtained showed that the infectious activity of the bacillus was completely inactivated by heating at 55°C for 30 min, or by exposure at a distance of 15cm for 120min. to a germicidal lamp (Shimazu GL-15). Furthermore, the infectivity of the bacillus was lost by agitation. (90/min) in a water-bath at 37°C for 5 days, whereas it was maintained for 10 days under the stationary condition.
